Today however some user agents (IE5+, Netscape6+) will interpret the HTML
and CSS in different ways if the DTD is present versus absent. Typically
without a DTD the UA will try to emulate past old, buggy behavior in
previous versions of itself, where with a current, correct DTD it will
follow the standards more correctly. So to get consistent results that you
can count on, including a DTD can be very important.
